Is it possible to inject a PTP clock for the CM4?
ptp3l is supposed to steer the internal oscillator (RC presumably), but depending on the version of ptp4l tested, it either can't lock, or loses lock after a few hours.
I have a nice stable clock that can produce arbitrary frequencies, but it seems like there is no way to inject that clock into the CM4. Is that correct?
I'm trying to debug ptp4l to see why it can't stay locked, but not getting very far.
